Any help here?Running Elyssa, with newest virtualbox in repo - same as on their site.I get:VirtualBox: supR3HardenedMainGetTrustedMain: dlopen("/usr/lib/virtualbox/VirtualBox.so",) failed: /usr/lib/libQtGui.so.4: undefined symbol: _ZN23QCoreApplicationPrivate19checkReceiverThreadE P7QObject

SOLVED:Following the spirit and sense indicated by a reply in the VirtualBox forum, I found I had both libqtcore4 and libqt4-core installed. I removed the first and reinstalled the second, and lo, virtualbox launches.
